I use the following: mpirun -machinefile machine.file -np 8 ./mpi-program and the machine file has the following:
t01 t01 t01 t01 t01 t01 t01 t01 I get the following error: rm_12992: (0.632812) net_send: could not write to fd=4, errno = 32 rm_13053: (0.421875) net_send: could not write to fd=4, errno = 32 rm_l_3_13050: (0.636719) net_send: could not write to fd=5, errno = 32 rm_13114: (0.210938) net_send: could not write to fd=4, errno = 32 rm_12870: (1.066406) net_send: could not write to fd=4, errno = 32 rm_12931: (0.855469) net_send: could not write to fd=4, errno = 32 rm_l_4_13111: (0.425781) net_send: could not write to fd=5, errno = 32 rm_l_1_12929: (1.070312) net_send: could not write to fd=5, errno = 32 rm_l_2_12989: (0.859375) net_send: could not write to fd=5, errno = 32 rm_l_5_13172: (0.214844) net_send: could not write to fd=5, errno = 32 p0_12866: (5.285156) net_send: could not write to fd=4, errno = 32 If I use np=6 or less, it works fine. It also works with 8 if the machine.file just contains t01:8 Since we want to submit this to a torque/moab cluster, it's not possible to get the latter format.
